TIME-CONTROLLED PHONOGRAPH STARTING DEVICE.

Application tiled May 10, 1923.

To all whom it may concern.'

Be it known that I, EMiLio PRovENzANo, a subject of the King of Italy (having declared his intention of becoming a citizen of the United States), residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Time- Controlled Phonograph Starting Devices, of which the following is a specification.

My invention relates to time-controlled phonograph starting devices and its object is to provide such a device which will lit anI size phonograph, may be easily applied, wi l not interfere with the regular playing of the phonograph and which is of simple and durable construction.

This object, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in Which- Figure 1 is a plan view of a phonograph having my invention applied thereto,

Figure 2 an inverted sectional plan view of Figure 1, illustrating the under side of my invention, and

Figure 3 an enlarged section taken substantially on line 3-3 of Figure 1, the phonograph being omitted.

Referring to the drawings, 1 is a phonograph cabinet, 2 the turntable, 3 the stopping lever, 4 the tone arm and 5 the tone arm supporting base. My invention includes a frame 6 stamped from sheet metal and preferably of the form shown. The frame is provided with extensions 7, 8 and 9 formed to provide guideways 10 for receiving securing arms 11, 12 and 13 respectively. Set screws 14 on the extensions secure the arms in position. The arm 11 engages the base of the tone' arm and the arms 12 and 13 engage the cabinet. The ends of the arms are preferably provided with felt or other like material so that the parts which the securing arms engage will not be marred. The frame is s'u ported on the cabinet by downwardly bent egs 15. Standards 16 and 16, integral with the frame, receive an alarm clock 17. Stand* ards 16 are provided with notches 18 which receive clock-supporting legs 19 and there by prevent turning of the clock. A plunger supporting arm 2O is integral with the frame and extends toward the stopping lever 3. The end of the arm is bent down- Serial N0. 637,979.

ward to provide a stopping leg 21 which serves to slidably receive a plunger 22 which has one end 23 engaging the stopping lever 3. The other end 24 is pivotally connected to an actuating link 25 which is pivoted to the frame at 26. An idler link 27 is pivoted to the frame at 28. A connecting bar 29 pivotally connects the ends of the links at 80 and is provided with a lug 31 adapted to engage and be actuated by a winding lever 32 on the alarm winding stem 33 of alarm clock 17. A spring 34 is connected to the frame and the lug and serves to return the movable parts into their normal position.

To apply my invention to a phonograph, the frame is placed with its legs 15 resting on the top board 35, and the arms 11, 12 and 13 moved until they engage the tone arm base and the sides of the cabinet re spectively. The frame is adjusted so that the end 23 of the plunger will barely touch the stopping lever. The arms are then secured to the extensions by tightening the set screws 14.

To use my invention, the alarm clock is wound by the winding lever 32 in the usual manner and the alarm set for the desired time. The clock is then placed between the standards so that its legs 19 will be within the notches 18 of the standards 16at and the Winding lever substantially in the position shown in Figure 2, engaging the lug 31 or nearly so. The sound box and tone arm are put in position on the record ready for playmg. Then the alarm is set o the winding lever will turn in the opposite direction to that when it was wound as shown by the arrow in Figure 2 and move the lug 81 which causes the plunger 22 to move the stopping lever 3 and release the turntable 2 as shown in dot-and-dash lines in Figure 2. The turntable will then start to rotate and the record will be played. After the movable parts have reached the position shown in dot-and-dash lines in Figure 2 the spring 34 will return them to their normal position and the Winding lever 82 will move around until it engages a stop 36 integral with the frame. By constructing a timecontrolled phonograph stopping device as above described the phonograph may be played in the regular way without interference by the device. The device will t any size machine, it being merely necessary to adjust the arms 11, 12 and 18.

By providing simple parts which are Cil easily stamped from sheet metal, the device is produced at a low cost.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed Without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come Within the scope ot the yappended claims. Y

Having thus described my invention7 what I claim as nen7 and desire to secure by Letters Patents is l.
